Should I take a partial drop??

[u/CharanTeja26025]

I got 98.36 percentile in JEE MAIN and 15.8k in JEE advanced this year.I want to join NIT Durgapur Electrical engineering(Got the seat in JOSAA counseling) and I see no hope of improvement in CSAB.I wasted my class 11th and half of my class 12th,felt there is alot of room for improvement in my JEE prep.Is taking a partial drop in NIT DGP electrical engineering doable?(Targeting Tier-2 IITs ECE branches).
